</p> <p> 現(xiàn)在的方矩管的型號(hào)以及種類的數(shù)量是很多的。現(xiàn)在在建筑還是其他的方面上方矩管的數(shù)量的運(yùn)用上是極為可觀的?，F(xiàn)在的一些建筑物上就會(huì)經(jīng)常的用到鋼管?，F(xiàn)在的一些重要的建筑物的重要的部件還是嚴(yán)格的要求要使用無(wú)縫鋼管，但是在價(jià)錢(qián)上面無(wú)縫鋼管的價(jià)格還是太高了，焊管的價(jià)錢(qián)要比無(wú)縫鋼管的價(jià)格要便宜些，還有就是焊管的直徑可以做得比無(wú)縫鋼管的直徑大些，在這個(gè)情況的影響下現(xiàn)在的許多的建筑物的大部分的構(gòu)件還是會(huì)采用焊管。 </p><p> 鍍鋅管 </p> <p> 又稱鍍鋅鋼管，分熱鍍鋅和電鍍鋅兩種，熱鍍鋅鍍鋅層厚，具有鍍層均勻，附著力強(qiáng)，使用壽命長(zhǎng)等優(yōu)點(diǎn)。電鍍鋅成本低，表面不是很光滑，其本身的耐腐蝕性比熱鍍鋅管差很多。 </p> <p> 熱鍍鋅管 <p> 是使熔融金屬與鐵基體反應(yīng)而產(chǎn)生合金層，從而使基體和鍍層二者相結(jié)合。熱鍍鋅是先將鋼管進(jìn)行酸洗，為了去除鋼管表面的氧化鐵，酸洗后，通過(guò)氯化銨或氯化鋅水溶液或氯化銨和氯化鋅混合水溶液槽中進(jìn)行清洗，然后送入熱浸鍍槽中。熱鍍鋅具有鍍層均勻，附著力強(qiáng)，使用壽命長(zhǎng)等優(yōu)點(diǎn)。北方大部分工藝采用鍍鋅帶直接卷管補(bǔ)鋅工藝。
